High CVSS 7.5

CVE-2026-56842

Ui Unifi Network Application

A malicious actor with access to the network and under certain conditions could exploit an Incorrect Authorization vulnerability found in UniFi Network Application to persist privileges within UniFi Network Application after such access had been removed.

What this means

Exposure
Exploitable remotely over the network, with an ordinary user account and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Weakness
An authorisation check exists but its logic is wrong.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.
